Abstract


Urban Heat Island (UHI) is a phenomenon which is affected by human activities. Land use change by human
activities, expressed by urbanization that means rural or suburban areas changed to urban areas. This study is
intended to identify the UHI phenomena in Tangerang city. To answer the aim of this research,temperature data
is collected (direct and indirect data). Direct collection for air surface temperature conducted by surveying
some location collect in 24 hour period (April 2012) and another location by rapid 10 – 15 minute in day time
(April, July, August and September 2012). This technique employed mobile temperature and humidity tools.
Secondary air surface temperature data (24 hour period) during 2009-2012 also use in this study. Indirect data
employed Landsat TM only two year data 2001 and 2012 for land surface temperature. Satellite data employed
to identify land cover change to get information about land use change. The result shown that the temperature
condition, both air surface and land surface temperature, were changed. UHI phenomenon in Tangerang City
indicated by temperature higher than 300C. Based on land surface temperature, UHI phenomenon in 2001
already occurred at small area. UHI phenomenon in 2012 almost covered the Tangerang City area. UHI Index
in 2009 is 3.60C, in 2011 is 1.50C and then 2012 become 1.20C. This study concludes that UHI phenomena
found since 2001 and trend of UHI Index AST since 2009 with average UHI Index AST of 20C. UHI Index LST
in 2001 is 9.780C and 2012 is 13.960C
